This fabulous Southwestern Zucchini Ham Crustless Quiche is healthy, hearty and super delicious. It comes together quickly and is a great way to use up leftover ham (or just purchase a chunk of ham from the deli)!
I've had Southwestern cuisine on my mind ever since we spent a few weeks in Phoenix, earlier this spring. It was a wonderful time, spending time with family along with lots of culinary inspiration. We'll be sharing a few more recipes over the next couple of weeks that are the result of that fun trip, one of them being this delicious Southwestern Zucchini Ham Crustless Quiche.

It's super easy to throw together, is a great way to use up leftover ham and makes a fabulous breakfast, lunch or dinner.
Healthy and hearty
Although we really enjoy quiches with a nice crisp crust, like this Easy Zucchini Summer Quiche, it's really nice to be able to cut back on carbs a bit without compromising delicious flavor.

Healthy and hearty
This Southwestern Zucchini Ham Crustless Quiche is hearty and satisfying with lots of lean protein. It also incorporates zucchini, which is rich in vitamins, minerals, and plant compounds. The recipe also includes lots of diced green chilis which also contain a surprising number of health benefits such as antioxidants, vitamins and the ability to help speed up metabolism.
Green chilis are mild so this isn't a spicy dish, but they give this Southwestern Zucchini Ham Crustless Quiche delicious South-of-the-Border flavor and pair fabulously with the sharp white cheddar cheese. You can find canned, mild green chilis in the international aisle of any larger grocery store in the Hispanic section.

How to serve this Southwestern Zucchini Ham Crustless Quiche
We've enjoyed this quiche for breakfast, lunch and dinner. For breakfast, it's nice served with some fresh fruit on the side. If you want to serve an extra special breakfast, make a batch of these Raspberry Scones or these Ridiculously Easy Buttermilk Biscuits. For lunch or a casual dinner, we really enjoy pairing this quiche with a simple green salad drizzled with this Spicy Cilantro Lime Dressing or this Sweet and Spicy Mango Dressing.
This Southwestern Zucchini Ham Crustless Quiche reheats nicely, but it's also delicious served cold, making it perfect for quick breakfasts on the run as well as work/school lunches.

The ease of crustless quiche
If you're intimidated by the idea of making quiche, you need to try this Southwestern Zucchini Ham Crustless Quiche! Crustless quiches are amazingly easy to make because, as the name suggests, there's no fussing with the crust. Just layer the ingredients in the pan, whisk together the egg mixture and pour it over the top. Then bake until it's nicely done and... enjoy! Super easy, super delicious!
The only real concern with this Southwestern Zucchini Ham Crustless Quiche is making sure the zucchini doesn't exude a lot of moisture during baking, making the quiche watery, bland and unattractive. That's an easy solution though... before you do anything else, simply slice the zucchini nice and thin, sprinkle it with a bit of salt then place the salted zucchini in a sieve. You'll be shocked at how much liquid is released while you proceed with the recipe! The salt draws the water out of the zucchini (osmosis) rendering it perfect for this crustless quiche recipe.

Café Tips for making this Southwestern Zucchini Ham Crustless Quiche
- Don't skip the step of salting and draining the zucchini. Zucchini is loaded with water and makes for a soggy quiche if you don't take this easy step.
- This recipe calls for diced green chilies. Green chiles can be found in small cans in the international aisle of most larger grocery stores in the area that stocks Mexican and Hispanic ingredients.
- This Southwestern Zucchini Ham Crustless Quiche rewarms well. I use low power (30-40%) in the microwave to slowly warm it without drying it out or making it tough.
- If your zucchini is large, cut it in half (lengthwise) before thinly slicing.
- This recipe works well with leftover ham. If you don't have leftover ham, you can purchase a chunk (or thick slices) of ham in the deli section of the grocery store. I like to use a smoky ham for this recipe. Boars Head makes a great smoky ham called Bold Bourbon Ridge Uncured Smoked Ham.
- If you don't live in the United States, you might not be familiar with half and half. It's an American convenience product often used for coffee. It's simply half milk and half cream. You could also use whole milk for this recipe instead.

Southwestern Zucchini Ham Crustless Quiche
Ingredients
- 1 medium-size zucchini
- 8 ounces canned mild green chilies, well-drained (I use 2 4-ounce cans)
- 1 ÂĽ cups diced smokey ham, (diced fairly small)
- 1 ½ cups grated sharp cheddar cheese
- 1 teaspoon dry oregano
- 5 large eggs
- Âľ cup half and half
- ½ teaspoon kosher salt
- ÂĽ teaspoon freshly ground black pepper
Instructions
- Preheat the oven to 350ËšF. Spray a 9-inch quiche pan or baking dish generously with non-stick baking spray.
- Slice the zucchini thinly and place in a sieve set in the sink or over a bowl. Sprinkle the zucchini with 1 teaspoon of kosher salt and toss with your hands. Allow to drain for 15-20 minutes then rinse the zucchini under cool running water. Transfer the slices to a clean kitchen towel and pat dry.
- Combine the drained green chilies, the ham, the zucchini and the cheese in a medium-size bowl. Stir gently to combine. Turn the mixture out into the prepared pan.
- Combine the eggs, half and half oregano, salt and pepper in a small bowl or measuring up and stir vigorously with a fork or whisk until well combined.
- Slowly pour the egg mixture over the filling working your way around the pan.
- Bake the quiche for 25-35 minutes or until the top is light golden and the filling is set. Let the quiche sit for 5 minutes to allow ingredients to set. Serve warm. This quiche can be made a day ahead, cooled and refrigerated. Before serving, rewarm in a 325ËšF oven for 15-20 minutes or microwave individual pieces on power level 4 for 2-3 minutes or until warmed all the way through.

My husband and I loved this recipe. I was wondering if you have ever frozen this? And if you have, do you freeze it before baking or after baking and then thaw and reheat?
Hi Terri, Thanks for the wonderful review! This quiche will freeze well and we recommend freezing it after baking. After letting it cool to room temperature, wrap it tightly in a layer of plastic wrap, followed by aluminum foil. You can freeze the quiche whole or sliced in individual portions. To reheat, thaw completely in the refrigerator, then bake at 350 until warmed through.
I really think a crustless quiche is just a baked omelette. The fact that you have a crust is because it will be fancy treat! I opt out of this !
Hi Narnie, no problem, we love that everyone has their own taste and opinion. We do have some great crusted quiche recipes that you would probably enjoy.
There are so many people (me included) these days who love a crustless quiche (aka a baked omelette, aka a frittata) because they have to watch their calories and like having healthy, high protein options for breakfast, brunch, lunch or dinner.
Oh, and if you happen try this recipe (it’s delicious!), come back and leave a star rating!
Make these at least once a week for a high protein lunch and or breakfast. So easy and good!
Thanks for the great review, T A! So glad to hear how much you enjoy this recipe - we appreciate you taking the time to let us know!
This quiche is divine. It was easy to make and just loved it. I like that the zucchini is sliced so you get nice pieces of zucchini in every bite. It is so filling, This will be one of my go-to recipes. I made two; one for us and one for someone having surgery, along with your Better than Starbucks blueberry muffins, which are also delicious. Made double so I could stick some in the freezer too. Thanks for keeping recipes simple.
Hi Vesta, Thank you for the excellent review! It's lovely to hear how well this recipe turned out for you, and we're always encouraged to know when recipes from the Café are delivered to bless friends and family. Thanks so much for taking the time to let us know how much you enjoyed the quiche (and the muffins!)!
This recipe makes a wonderful breakfast Chris! Flavors are delicious and the quiche is quite filling. Really like the zucchini sliced rather than shredded as is often done as it just gets lost in the quiche. I was careful to follow your instructions for the zucchini but only let it drain for 15 minutes; next time I think I might let it go 30 minutes. Also was careful to drain the ham which had been frozen. Despite this, I did get a bit of liquid coming off but not too much. Great recipe!
Thanks for your review, Norma!
Hi Chris,
What size is the baking dish? I'm guessing that PAM is good enough to prvent sticking or should I use Crisco? Could this quiche be done in a sprinform pan too or do you think it will leak out?
thank you!
Sandy
Hi Sandy, I use non-stick cooking spray and it worked fine. I was even able to slide it out of the pan onto a cutting board. I wouldn't use a springform though, as I'm pretty sure the egg mixture would leak.
Question: In the recipe you mention pouring the mixture "into the prepared pan". What size quiche pan did you use, and how did you prepare it? Thanks, Mary
Sorry, it's all there now. The first step somehow got cut off when I added the recipe.
What size pan, what temperature do you bake it at 🤷
Hi Phyllis, just saw that the first step, the prep, got cut off but I have added it!
Oven temp?
Sorry, somehow that first step got cut off. It's there now!
